where P is the maximum output
power rating of the transmitter in
watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in
metres (m). Field strengths from
fixed RF transmitters, as determined
by an electromagnetic site survey,a
should be less than the compliance
level in each frequency range.b
Interference may occur
in the vicinity of
equipment marked
with this symbol:
NOTE 1
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and l
and mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which the
“Daylight Lamp” is used exceeds the applicable RF compliance level above, the Medical Daylight should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the “Daylight Lamp”.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [
